During October and November, 1904, I had the pleasure of learning some interesting features of the habits of a certain group of moths which appear at that season of the year. The abundance of these species under seemingly very unfavourable climatic conditions was a great surpise to me. The observations made on these hardy creatures of the insect tribe may prove interesting to Lepidopterists who are willing to exert a bit of energy in the pursuit of their hobby. During the last few years I have learned that we must take the topography of the country into account in selecting a place to bait for the months, which appear after we have observed the first autumn frosts on the landscape.
